Our brains contain billions of cells. None of them does much alone; what matters is how they communicate and form networks. When large numbers of cells fire at the same time, the summed electrical activity can be measured at the scalp. Those rhythms are what people mean by brain waves.
What EEG measures
Electroencephalography (EEG) records the electrical activity of the brain through sensors placed against the scalp. It is a recording method, not a test that returns a verdict about a person. EEG shows how rhythms change from moment to moment: while resting, while concentrating on a task, while the room is noisy.
Where the idea of EEG self-regulation came from
Research into whether people can notice and change their own brain rhythms goes back to the late 1950s and early 1960s, with work by Joe Kamiya at the University of Chicago and Barry Sterman at UCLA. Those studies established that people can learn to shift a rhythm when they are shown it in real time. That is the general research background of the field; it is not evidence about any particular product.
What Auto Train Brain does
Auto Train Brain reads EEG from a consumer headband and turns it into on-screen exercises. Nothing is administered and nothing is stimulated: the sensors only read. During a session the app shows the user what their own recorded rhythms are doing while they work through attention, memory and reading-practice exercises, and it keeps a record of each session so a family can see how often they practised and how the numbers moved.
What we do not claim
Auto Train Brain is not a medical device. It is not intended to diagnose, treat, cure or prevent any disease or condition, and it is not a substitute for education, tutoring or care from a qualified professional. We do not claim that it replaces anything a teacher or a professional provides, and we do not make claims about outcomes for any medical condition. Published research on the approach is listed on our research articles page; those studies were small and their results should be read as preliminary.
Who tends to get on with it
The families who report the steadiest experience are the ones who can fit a short session into an ordinary weekday and keep doing it. A quiet corner, a predictable time of day and realistic expectations matter more than intensity.
